MULTIPLE SCREW-DRIVER.

SPECIFICATION forming part of Letters Patent No. 532,823, dated January22, 1895.

Application filed August 22,1894. Serial No. 521,001. (No model.)

To a whom it may concern:

Be it known that I, HARRY F. SANGER, of Lima, in the county ofLivingston and State of New York, have invented a new and usefulImprovement in Multiple Screw-Drivers, which improvement is fully setforth in the following specification and shown in the accompanyingdrawings.

My invention is an instrument designed more particularly for jewelersand machinists use, consisting of a hollow cylindrical case holdingcertain tools useful in such trades, and convenient means for bringingany one of the different tools quicklyinto position for use when needed.The form and construction of the case are such that the latterconstitutes a handle for the tool when in position for use. 1

The invention is hereinafter fully described and more particularlypointed out in the claims. I

Referring to the drawings: Figure 1 is an elevation of the device whenready for use. Fig. 2 is a longitudinal section upon the dotted line 2 2in Fig. 6, along the axis of the case, showinginterior parts. Fig. 3 isa similar section of a portion of the case and interior parts, partsbeing broken away and other parts shown in various positions by full anddotted lines. Fig. 4 shows the spindle more fully and some associatedparts longitudinally sectioned and broken away. Fig. 5 is an end view ofthe cap for the case, the spindle being transversely sectioned on thedotted line 5 5 in Fig. 1. Fig. 6 is a view of the upper end of thedevice. Fig. 7 is a transverse section of the spindle on the dotted line7 7 in Fig. 4, showing the core-piece. Fig. 8 is a transverse section ofthe core head and spindle on' thedotted line 8 8 in Fig. 4. Fig. 9 is atransverse section of the case, tool cells and spindle, on the dottedline 9 9 in Fig. 2. Fig. 10 is a transverse section of the case and toolcells on the dotted line 10 10 in Fig. 2, the spindle being sectioned onthe dotted line .10 10 in Fig. 4. Fig. 11 is an upper end 8. Figs. 14and 15 show tools of difl'erent sizes. Fig. 16 is an end View of a tool.

The figures are drawn to a scale twice the size of the device asdesigned for j ewelers use. v Referring to the parts shown, A is thecase of the device it being made of sheet metal hollow, cylindrical inform and provided with a closing cap I) for the upper end and a reducedopen tube or nozzle d covering its lower end. The cap and nozzle aresecured rigidly to the case by some simple means as, for instance, beingscrew-threaded thereon. W ithin the case is placed a core-piece B, Fig.2, formed with a cylindrical head g, Figs. 4 and 7, at its upper end anda corresponding circular plate h, Fig. 10, at its lower end, the headand plate having diameters corresponding with the internal diameter ofthe case and held from turning therein by friction. The core-piece isfurther provided with a series of longitudinal, uniform, peripheralcells a for holding tools, a, which as shown are a series of screw-drivers of different sizes fully shown in Figs. 14 and 15 and otherfigures; the cells,

vwithin the case. 1 The cells a, which are shown as three in number, arecontiguous with the wall of the case the spindle occupying the centralspace therein. a

E, Fig. 2, is an inclined chute or conductor ,for the tools, below thecore-piece, formed at its upper end with a cylindrical head e, Fig. 11,having a diameter corresponding with the internal diameter of the case,the chute being adapted toturn within the case around the axis of thelatter. The head of the chute is contiguous with the lower end of thecorepiece the lower end of the chute resting concentricallywithin thenozzle, as shown in Figs. 2 and 3. The bore lot the chute correspondswith the bore of a cell and the upper end of the chute is inclined toone side contiguous with the wall of. the case so" that the upper end ofthe bore of the chute may be. brought to register with the lower end ofany cell by turning the chute within the case.

The lower portion of the spindle is prismatic, of square cross section,as shown in Fig. 10, and passesfreely through a circular opening in theplate hot the core-piece. This squared part of the spindle also passesthrough a square opening in the head 6 of the chute with a sliding fit,as shown in Fig. 11, and occupies a longitudinal slot z' in the inclinedside of the chute, see Figs. 2 and 12, with its lower end projectingbelow the lower end of the chute and slightly below the nozzle.

The head g of the core-piece is formed with a central, longitudinalsleeve k, Figs. 4 and 7, through which the spindle passes and with inwhich it may either turn, or slide longitudinally, the sleeve forming abearing for the spindle. WVhen the spindle is turned on its axis itturns the chute within the case on account of the squared part of thespindle fitting the square hole in the head of the chute, said headconstituting practically a lower bearing for the spindle. By turning thespindle (by applying the thumb and finger to the head f) the chute maybe controlled and brought to register with any one of the cells and soform a continuous passage from the cell to the opening in the nozzle bymeans of which any one of the tools may be brought into position for useat will, as appears in Fig. l.

The tools are formed with slight shoulders 'v and the bore of the nozzleis formed with a corresponding internal shoulder to meet the shoulder ofthe tool, which prevents the latter from passing out through the nozzlewhen it drops into position therein, as stated.

The heads of the tools are formed with central longitudinal cavitiessquare in cross section a part of the way, and of a size to fit the endof the spindle so as to be turned by the latter, as shown in Fig. 4. Theend of the spindle fitting the cavity in the tool enables the spindle tohold the tool from being pushed upward in the nozzle when pressed downagainst the Work while in use. The extreme end of the spindle is reducedand made round so as to better enter the cavity in the tool. When thetool is to be returned to its cell after use, the spindle is drawnupward and the case inverted to allow the tool to drop back into itscell after which the spindle is again pushed inward to its normalposition, as appears in Fig. 2 and in full lines in Fig. 3. A portion ofthe spindle toward its upper end is given the form of a triangular prismthe three faces corresponding with the number of the tool cells. In thehead g of the corepiece is placed a transverse detent spring 02, Figs.4, 7 and 8, in position to bear againsta face of the triangular prismand prevent the spindle from turning. This spring has its ends securedin the outer shell of thehead g, a notch o in the sleeve 7c, Figs. 8 and13, making way for the spring where it passes said sleeve. Now, theconstruction of the parts is such that when a face of the prismcoincides with the spring the chute is in position to register with someone of the cells, and the spring holds the parts relatively in place.The spindle is, however, formed with a reduced part or notch 19 Fig. 4,at the lower end of the triangular prism which, when opposite thespring, permits of the spindle being turned to any one of the threepositions, this notch or reduced part being presented to the spring whenthe spindle is drawn out, as above stated, and indicated by dottedposition in Fig. 3. The notch is formed withinclined and vertical flatfaces to, being downward continuations of the respective faces of theprism, on account of which though the spindle may be turned its turningis gently resisted by the spring. This form of the spindle is for thepurpose of enabling the spring to hold it relatively in such a positionthat when pushed downward the spring will be sure to glide onto a faceof the prism and not onto an edge of the latter between two faces. Whenthe spindle is drawn out and the detent spring occupies the notch 19,its edge coming in contact with the larger part of the spindle below thenotch acts as a stop to prevent the spindle being drawn farther out.

The cells, which are open on their sides next the wall of the case, aredesignated by numbers, marked on the cap I) as shown in Figs. 1, 3 and5, the numbers corresponding to the sizes of the screw-drivers; forinstance, 1, 2, 3 corresponding with the screwdrivers in the order fromthe smallest to the largest. The cap I) of the case is formed with threeequally spaced, longitudinal perforations 7' and the head fof thespindle is provided with a longitudinal, rigid pin .9, Figs. 2 and 4, inposition to enter any one of these perforations. Perforation No. 3, forexample, corresponds to cell holding screw-driver No. 3 size; and whenthe spindle is turned so the pin will enter the perforation No. 3 thechute will be in position to convey screw-driver No. 3into the nozzle,for use. The head a of the chute being imperforate save as to theopening of the bore Z and the central opening to receive the spindle,serves to close in every case the two cells other than the one thenacting with the chute, and prevents the escape of the tools in thosecells.

When the device is being used all parts turn together as if of onepiece, except as to the loose button D which may turn independently ofthe other parts at all times; and it forms a carrier for the thumb andfinger to ride back upon to catch a new hold of the case to turn thescrew being acted upon.

In preparing to use the device at any time it is turned head downward sothat all the tools will occupy the respective cells from the action ofgravity. The spindle is then drawn out and turned to the number of theparticular tool required when the case is again turned nozzle downwardwhich causes the selected,

15001 to drop into the nozzle, through the chute. The spindle is thenforced down into and against the tool, as stated, the device then beingready for use.

In case when picking up the instrument for use at any time the spindleis in position for ICO the particular tool desired, the case beingturned nozzle downward the tool will drop" nozzle, after which thespindle is pressed down upon it as in the other case mentioned.
